` March TITTTIED STATE@ PATENT WILLIAM rHoi/IAsJAMEs, or CHICAGO,ILLINOIS.

Original application led March 30, 1908,"Seria1 No. 424,242. Divided 8,1910.` Serial No. 576,183.

To allwwm it may concern:

Be it known that I, WILLIAM THOMAS JAMES, a citizen of the UnitedStates, residing at Chicago, in the county of -Cook and State ofIllinois, have invented certain new and useful Improvements inConveyers, of which the following is a speciiication. j

rIhis invention has reference to the provision of an improved form ofapparatus for handling coal or other like material in bulk, certainstructures in which itis convenicntly employed being shown in mycopending application, Serial No. 424,242, filed 30, 1908, of which thisis a division. The invention has for itsprimary objects, the provisionof an improved form of conveyer chain having buckets mounted therein, animproved form of .stop device for alfording a support for the bucketwhile` it is in loaded position, and also acting as a `stop for themovement. of the bucket when it is tripped in dumping the material, andto provide an improved form of'construction for tripping the bucketVwhen traveling in a nonhorizontal or vertical plane, which said tripdevice is constructed so that it can be thrown into and out of positionat will-depending upon the place at which the bucket is intended to dumpits contents. `30

A further object of the invention is the provision of a carrier chain ofthis general type, composed of link sections each having one bifurcatedend and one single or plain end, and means forengaging saidV ends of theadjacent sections together, such link sectionsbeing provided withbucketesupporting v means intermediate the ends.`

The above, as well as such other objects as may hereinafter appear,Iattain by means of a construction which I have illustrated in preferredform in the accompanying drawings, wherein l Figure 1 shows in sideelevation the upper end of a` conveyer embodying my improvement; i

Fig. 2 `is another partial view.in elevation-of the apparatus shown inFig. 1;

,Figf 3 is a View of several of the buckets carried by the chain, shownas moving in vertical direction, with one of thebuckets justdumped todischarge its contents;

1 Fig. 4 isanotherview of the apparatus shovnin Fig. 3,; showing it in adierent elm/atterra j coni/*Erna Speccation of Letters Patent.

1 to 4 inclusive, it will upper ends of rockerarms and this applicationled August Fig. 5 is a view showing a slightly modified form of thedumping device, and

Fig 6 is a view in elevation of the mechanlsm shown in Fig. 5.

Referring now more particularly to Figs. be seen that I have thereinAindicated a conveyer chain 7 arranged to be carried at its upper end bya suitable sprocket 8 mounted on a shaft 9 on the other end whereof is asimilar sprocket carrying a. similar chain or portion of conveyer belt,between which portions of the conveyer belt I mount a plurality ofbuckets 10 `as shown, the same being adapted to travel in a path wherethe material is lifted vertically as indicated by the arrow in Fig. 3,and arranged to be dumped while the buckets are traveling in a verticaldirection upward, as shown in saidFig. 3, into some suitable trough orother receptacle 11, by means of the tripping arrangement to behereinafter more particularly described.

The side parts of the conveyer chain are composed of links indicated inFigs. 2, 4, and 6 particularly, such link members 13 having bifurcatedupper ends at 14 and plain lower ends as indicated at 15, the plain endsbeing engaged within the bifurcated ends as shown, and the whole heldtogether by suitable fastening bolts or other devices 16. Intermediatethe ends of the link members 13 is a hub 17 through which extends thetrunnion or support 18 which serves for carrying the bucket 10, therebeing a trunnion support at each end as shown, and each end of thebucket being provided with an angle-iron projection or bracket 19preferably secured by rivets 20, with the iange 21 thereof extendinglaterally in position such as will engage with the trip roller 22 whenthe latter is in position for dumping the bucket, bringing the same intothe position indicated in full lines in Fig. 3, in which the contentswill be discharged into the trough 11 or any other suitable receptacle.

The trip roller -22 has a counterpart on the other side of the bucket,so that the brackets 19 will have simultaneous engagement on both sidesof the bucket to take the strain better, and the rollers are carriedupon the 23 mounted on rockereshafts 24, so that if desired, asindicated yin Figs. tend 5, therollers 2.2 can be aimultaneeuely swungte the right cut.

the buckets to pass without dumping, whereby if another tripA device orpair of'levers 23 carrying similar rollei's 22 is mounted in anotherpart of the path oi' movement ot the buckets, the contents oi the bucketcan be dumped in such other position, as for example where it isrequired to distribute the contents oi the' buckets lirst in onehorizontal plane and later in another higher horizontal plane as thebins or receptacles below become iilled.

As a ineans for 'connecting together' tlie two conveyer chains I providea strap or connecting device Q5, indicated more plainly perhaps inFig.t, and said strap Q5 is secured to the side links as indicated at 26,whereby it holds the said side links in proper relative position, andalso serves as a stop for the buckets 10, being so placed as to stop thebuckets both in the loaded and inthe unloaded position, as plainlyindicated in the several Iigures.`

This strap or connectingdevice 25 also serves to permit the bucket vtoright itself into operative position after, having discharged itsrcontents, the bucket being stopped in such vertical position by contactwith the rear edge/ot the stop which, upon reference to Fig. 3, will beseen to be slightly inclined from the perpendicular.

Having thus described my invention and illustra-ted its use, what Iclaim as new and desire to secure by Letters Patent, is the following:

l. In a material handling apparatus in combination, a pair of opposingcarriers each composed of a pair of chains, each comprising a pluralityof link sections, means connecting the ends oil adjacent sectionstogetlier, a conveyer bucket pivotally mounted between the cari'iers,and means between the carriers adjacent said bucket for stopping thebucket in bothits loaded and unloaded positions.

2. In a' material handling apparatus, a

pair of opposing carriers, a normally swing-V ing conveyer bucketpivoted between said carriers, and means connecting said carrierstogether for stopping the bucket in botlr'its loaded and unloadedposition, said-last mentioned means being so constructed as to per-l mitthe bucket to right itself into operative position after discharging itscontents.- 3In a material handling apparatus, a pair of opposingcarriers, a conveye'r bucket pivotally mounted between said carriers,and a bar between the carriers located adjacent the bucket, for stoppingthe bucket in both its loaded and unloaded positions.
